Okay, so I didn't get it all but 100% Minyoung have been paying back Cheol's trashy family by secretly having someone beat up the scum little brother. That brat really got himself cursed by atracting Minyoung's never ending ire
I thought it was just another way for Cheol to depend on him, he's slowly trying to isolate him from his family before trying to cut them off all together by outting him is my suspicion. It's isolating your victim. Even if it does end up for a better future for Cheol, it is unconsentually done.
